My Lords, between 2010 and 2014, the MoD destroyed 43 Challenger 2 tanks, regarded at the time as being beyond any economic repair. These destroyed tanks, however, could have gone to Ukraine or other NATO allies. This new information has highlighted the government policy with respect to stockpiling, storing or mothballing old equipment. Can the Minister tell us what the current government policy on old equipment actually is? Is any review taking place to ensure that such a policy helps guard against future unknowns and emerging threats in an increasingly challenging strategic environment?
